White House press secretary Jen Psaki spoke with journalists on Air Force One en route to Kalamazoo, Michigan, where Biden will tour a Pfizer vaccine facility and deliver remarks Friday.

Psaki said the president wanted to see the factory in action because it employs many Michiganders and because it is "producing a large swath of the Pfizer vaccines that are going out to the American public." She also said that the factory benefitted from Biden invoking the Defense Production Act.

"The administration engaged with Pfizer suppliers to obtain the equipment needed to expand manufacturing capacity, including at the facility in Kalamazoo," Psaki said.

After his virtual address at the Munich Security Conference, Biden responded to questions about the weather in Texas and confirmed he is considering visiting the state next week but wants to make sure his visit won't burden people responding to the crisis.

"If in fact it’s concluded that I can do without creating a burden for the folks on the ground when they’re dealing with this crisis, I plan on going," Biden said.

Biden also confirmed he would soon sign a major disaster declaration for Texas, in addition to the emergency declaration he signed Sunday. Biden took the opportunity to tout his efforts on Texas' behalf as keeping a campaign promise to be a president for all Americans.

"It’s all about commitment to the American people -- that people make to one another -- so we’re gonna sign that declaration once it’s in front of me," Biden said.

With the major disaster declaration, Biden will direct more federal agencies, including the Department of Health and Human Services and the Department of Defense, to identify additional resources to help Texans, in addition to the help FEMA is already providing.

During remarks at the Munich Security Conference on Friday, one of Biden's first appearances on the global stage, he emphasized a commitment to global alliances and democratic values. Biden's speech also contained a few thinly veiled jabs at former President Donald Trump and indications that Biden intends to reverse Trump's policies.

"I speak to you today as president of the United States, at the very start of my administration, and I'm sending a clear message to the world: America is back," Biden said. "The Transatlantic Alliance is back. And we are not looking backward, we are looking forward together."

Biden called on allies to come together to counter the threats from China and Russia and protect global security, and said the U.S. would rejoin negotiations on Iran's nuclear program. The president also stressed the need for a global response to climate change, touting America's return to the Paris Agreement.

The president also announced the U.S. will contribute $4 billion to the COVID response and vaccination and to global health systems.

"Today, I'm announcing that the United States is making a $2 billion pledge to COVAX, with the promise of an additional $2 billion to urge others to step up as well," Biden said. "Even as we fight to get out of the teeth of the pandemic, the resurgence of Ebola in Africa is a stark reminder that we must simultaneously work to finally finance health security, strengthen global health systems, and create early warning systems to prevent, detect and respond to future biological threats because they will keep coming."

Biden announced the addition of key officials in the Department of Health and Human Services, Department of Education and the Department of Veterans Affairs on Friday morning.

Chiquita Brooks-LaSure will serve as the administrator for the Centers for Medicare and Medicaid Services, James Kvaal will serve as under secretary of education, and Richard Sauber will serve as general counsel for the U.S. Department of Veterans Affairs.

The White House statement added that the hires would, "build a stronger, more resilient, and more inclusive nation."
